Answer:
At each <u>intervertebral </u>foramen, the dura mater extends between adjacent vertebrae and fuses with the connective tissue layers that surround the <u>spinal nerves. </u>
Explanation:
The dura mater is the outermost meninge. It is around the spinal cord and the brain, and it protects these organs. In the spine, the dura mater extends between the intervertebral foramen. The intervertebral foramina are the areas between each vertebra that have spinal nerve projections. In these areas, the dura mater extends to seclude the space where the spinal cord is since it fusses with the tissue that is around each spinal nerve to stop the entrance of any pathogen to the spinal canal, which is the space that contains the spinal cord.
The histones are present in the chromatin. The histones are composed of a histone core and a linker. The histone core is composed of H2A, H2B, H3, and H4. However, the linker is composed primarily by H1; which is not part of the histone core.
